Wiper Motor or Switch???? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok, see if you guys can figure this one out.

My wipers only have one speed. Moving the switch from the slow position to the fast position results in no change to the speed. Seems to be stuck on slow speed. After the wipers have been working for 15 or so minutes, I can't turn them off. They almost stop at the bottom, but they just keep going. The only way to stop them is to turn the key to off.

I changed the switch out.

I changed the motor out.

The problem persists.

Any thoughts?

Thanks!

My guess is the wiper motor assembly. They're a pain to change , unless your truck is disassembled like mine.

how's the ground at the switch? IIRC these systems the switch grounds the motor. maybe a bad connection at the switch wiring or motor?
they work almost the opposite of a blower motor.
